使用CSS和HTML进度栏布局

Question

我正在尝试实现UI,如图所示.然而,在尝试定位组合之后,我现在很难,但我一无所知.有人可以帮我弄这个吗？

<style>
    .progress{
        position:relative;
        width:500px;
    }
    .bar{

    }
    .percent{

    }
</style>
<div class="progress">
    <span class="bar" width="%"></span>
    <span class="percent">50%</span>
</div>

Answer 1

HTML:

<div id="progress">
    <span id="percent">30%</span>
    <div id="bar"></div>
</div>

CSS:

#progress {
 width: 500px;   
 border: 1px solid black;
 position: relative;
 padding: 3px;
}

#percent {
 position: absolute;   
 left: 50%;
}

#bar {
 height: 20px;
 background-color: green;
 width: 30%;
}

Answer 2

.progress{
        position:relative;
        width:500px;
        border:1px solid #333;
        position:relative;
        padding:3px;
    }
    .bar{
        background-color:#00ff00;
        width:50%;
        height:20px;
        transition:width 150ms;
    }
    .percent{
        position:absolute;
        display:inline-block;
        top:3px;
        left:50%;
        transform:translateX(-50%);
    }

<div class="progress">
    <div class="bar"></div >
    <div class="percent">50%</div >
</div>
